Answer:
y = -5/7x - 2/3
Step-by-step explanation:
Because the slope is -5/7, you multiply that by X.
Then you add -2/3, the y-intercept.
Answer:
see explanation
Step-by-step explanation:
Given
4x - 8x ÷ 2
Under the rules of PEMDAS , division must be performed before subtraction.
Hence
4x - 8x ÷ 2 = 4x - 4x ← dividing - 8x by 2, then
4x - 4x = 0 ← correct answer
There's nothing to multiply. However, you can factor it to get (x + 4)(x - 4).
Draw a right triangle to represent the problem.
The vertical height of the triangle is 9 ft, and it represents the tree.
The horizontal length, at the bottom of the tree is ground level and has a length of 13 ft.
Let x = angle of elevation.
By definition,
tan x = 9/13 = 0.6923
x = arctan(0.6923) = 34.7 deg. = 35 deg (approx)
Answer: 35°
